Some users did not understand the sand dryer when they first started, and they would have a question, why use a sand dryer to dry sand? What are the uses of river sand after being dried by a sand dryer? Many customers who want to invest in sand dryers will ask this question. As a manufacturer of sand dryers, our technical staff will answer the confusion that customers face from the general direction.
When the sand is first picked, it contains a lot of water. If the supply can keep up with the sales, it can be dried for a while. If the sales volume is large, natural drying is not enough. By drying and subdividing the sand by the sand dryer, the output can be increased efficiently and the sand has a wider market. There are many types of sand: river sand, yellow sand, sea sand, etc. These sands are classified according to different particle sizes, and different particle sizes have different purposes. The sand used in building insulation materials and the sand used to build houses are the same, but they also need to be classified. There is no way to classify sand when it is wet. At this time, you need to use a dryer to dry the sand and enter it into the vibrating screen. The size of the sand is separated and stored separately according to the number of screen meshes. The prices of different sands are also different when they are sold.
First of all, when the river sand is used in the insulation material industry after drying, the moisture content is generally controlled below 1%, because the insulation material is generally a material with a guiding thermal coefficient less than or equal to 0.2. In addition, the development of thermal insulation materials is very fast, and the use of good thermal insulation technology and materials in industry and construction can often achieve a multiplier effect with half the effort.
Secondly, the river sand can be used as a filling material after being dried. This industry mainly requires filling materials for the production of light industrial products. Generally, the demand is not too large. Customers can purchase a small sand dryer for investment.
Finally, the building materials industry in many places has developed rapidly. After drying, the sand can be used for building materials production, casting materials and abrasive construction.
